(Kitco News) - Altus Strategies (AIM:ALS)(TSXV:ALTS)(OTCQX:ALTUF) announces a significant increase to the Net Present Value ("NPV") generated by an update to the Preliminary Economic Assessment ("PEA") on its 100% owned Diba gold project in western Mali ("Mali").
The PEA has been updated to incorporate the significant increase in modelled oxide gold recoveries (from 80% to 95%), in line with the results of the metallurgical testwork undertaken on Diba drill core, as announced by the company on 28 October 2020.
At 10% discount rate and US$1,500/oz gold price, after-tax NPV is US$107 million with payback of 6.1 months; after-tax IRR is 715%. This projected open-pit heap leach operation has an average All-In Sustaining Costs of US$544/oz per year calculated at the PEA stage.
CEO Steven Poulton said that increase in the modelled gold recoveries contributed most to the significant NPV improvement.
"The updated PEA generates an impressive US$107 million after-tax NPV10 for just the oxide portion of the Diba gold project using a highly conservative US$1,500 per ounce gold price. The NPV10 increases to US$140 million at a US$1,800 per ounce gold price. This significant 32% increase in the NPV from the previous PEA (dated 22 July 2020) is a product of increasing the modelled oxide gold recoveries from 80% to 95%, in line with the results of the recently announced metallurgical testwork undertaken on Diba core. The PEA envisages a simple low-cost and low-strip ratio open-pit gold mine using standard heap-leach processing,” said Poulton.
Diba hosts a shallow dipping near-surface gold deposit with a Mineral Resource Estimate comprising: 4,834,000 tonnes at 1.39 g/t Au for 217,000 oz in the Indicated category; 5,479,000 tonnes at 1.06 g/t Au for 187,000 oz in the Inferred category.
